In this paper, a sliding mode control law is proposed for nonholonomic wheeled mobile robots using back-stepping technique. In order to resolve the speed jump problem existing in traditional sliding mode tracking controller, a novel sliding mode control law is designed based on neural dynamics model. The simulation results verify the effectiveness of the proposed controllers.
The development of atomic force microscopy (AFM) opens an entirely new way to investigate the dynamic changes of cellular structures, such as cell junctions and protein molecules. Since these structures are in nanometer scale, it cannot be observed and studied by conventional optical microscopy. Besides, AFM can also be used for precise manipulation of these nano-sized molecules such that the interaction...
This paper presents a high pulsed electric field generator for microbial inhibition of liquid food in continuous treatment applications. The proposed pulsed electric field generator adopts forward/flyback hybrid converters to achieve a bidirectional narrow pulse voltage output. With this circuit structure, the proposed one can reduce voltage stresses of output diodes and switches in secondary winding...
